DIY Phosphate Additive

[AlienReef]

Hello @Randy, I would like to know if I can use trisodium phosphate to create a solution to increase my phosphates? And if there is some measure per gallon of this solution to know how much it added to the system?
In my country, I can get trisodium phosphate, I don't know what grade it will be. Thank you so much!

Yes it is a good additive, assuming it is suitably pure.

Use this calculator and the entry for phosphate from potassium phosphate. it is close enough.
